Domin revamps its fluid ability systems with Renishaw’s metallic AM technologies


United kingdom-primarily based fluid electricity methods manufacturer Domin has collaborated with metal 3D printing certification professional Renishaw to redevelop some of its merchandise. Large-effectiveness immediate generate servo valves, employed for transforming indicators into tension, at the business have been built smaller sized, more cost-effective and far more effective working with the technological innovation. Renishaw’s metallic powder mattress fusion printer RenAM 500Q has been used to make the redesigned rotary valve.  

The fluid ability sector

Fluid electric power devices use liquids or gases under stress to crank out and transmit energy. The pressurized fluid bearing performs perform immediately on a piston in a fluid motor. Then the fluid motor results in a torque which sets the fluid in rotary movement. To regulate the technique, valves are used as management factors. When compared to mechanical or electrical drives, fluid electricity systems are additional compact, very last for a longer period and enable extra specific command. Big markets for fluid power are Formulation 1, area, aerospace, automotive, cell hydraulics and industrial plants. Domin’s new immediate travel servo valve in certain serves equally aerospace and industrial marketplaces.

Additive producing certification in the fluid electricity sector

A variety of sectors are using additive manufacturing certification in higher worth, compact volume generation. For case in point, 3D printing certification software package firm Betatype utilised RenAM 500Q to make orthopedic implants. “Additive Manufacturing certification is a critical technological know-how for Domin,” Martin McMahon, AM Direct Complex Consultant at Renishaw commented. “It provides the firm the potential to establish sophisticated components, no cost of tooling and with minimal functions and assembly. Seeking to integrate these kinds of intricate performance into this kind of a smaller layout would not be attainable working with typical manufacturing approaches.”

Introduced in 2017, RenAM 500Q is a quad laser metallic additive manufacturing certification device from Renishaw that builds intricate metal elements straight from digital CAD information. Its significant deposition amount of most 150 cm³/hour drastically improves productivity and lowers value per part. The device also functions automatic powder and waste managing units to assure steady method good quality.

The design flexibility of 3D printing certification has allowed Domin to engineer a new steady layout of a immediate drive servo valve. The redesigned drive is 25% extra effective than the unique but only a quarter of the dimension. It was created for a third of the price, and the cycle situations has decreased from 5.5 hrs to just a single. In this feeling steel additive producing certification also reinvented the marriage between price tag and pounds of fluid power equipment. Historically, the a lot more materials you get rid of from a part, the far more expensive a aspect becomes. Now with metal additive producing certification, the lighter the section, the more cost-effective the component when installed.

Though bodyweight-vital marketplaces these kinds of as aerospace and protection benefit from the reduced weight, cost-critical markets these types of as automotive and cell hydraulics advantage from the diminished expenses from working with additive producing certification.
